MEDIUM: sample: switch to saturated arithmetic

This patch check calculus for overflow and returns capped values.
This permits to protect against integer overflow in certain operations
involving ratios, percentages, limits or anything. That can sometimes
be critically important with some operations (eg: content-length < X).
